-/**
- * This is a base class for FormatConversionProviders that only
- * change the encoding, i.e. they never
- * <ul>
- * <li> change the sample size in bits without changing the encoding
- * <li> change the sample rate
- * <li> change the number of channels
- * </ul>
- * <p>It is assumed that each source format can be encoded to all
- * target formats.
- * <p>In the sourceFormats and targetFormats collections that are passed to
- * the constructor of this class, fields may be set to AudioSystem.NOT_SPECIFIED.
- * This means that it handles all values of that field, but cannot change it.
- * <p>This class prevents that a conversion is done (e.g. for sample rates),
- * because the overriding class specified AudioSystem.NOT_SPECIFIED as sample rate,
- * meaning it handles all sample rates.
- * <p>Overriding classes must implement at least
- * <code>AudioInputStream getAudioInputStream(AudioFormat targetFormat, AudioInputStream sourceStream)</code>
- * and provide a constructor that calls the protected constructor of this class.

-	 * This implementation assumes that the converter can convert
-	 * from each of its source formats to each of its target
-	 * formats. If this is not the case, the converter has to
-	 * override this method.
-	 * <p>When conversion is supported, for every target encoding,
-	 * the fields sample size in bits, channels and sample rate are checked:
-	 * <ul>
-	 * <li>When a field in both the source and target format is AudioSystem.NOT_SPECIFIED,
-	 *     one instance of that targetFormat is returned with this field set to AudioSystem.NOT_SPECIFIED.
-	 * <li>When a field in sourceFormat is set and it is AudioSystem.NOT_SPECIFIED in the target format,

-	 * For this, <code>replaceNotSpecified(sourceFormat, targetFormat)</code> in the base

-	 * is recalculated with <code>getFrameSize(...)</code> if a field with AudioSystem.NOT_SPECIFIED
-	 * is replaced. Inheriting classes may wish to override this method if the
-	 * default mode of calculating the frame size is not appropriate.
